Purchasing Power Parity - PPP
A theory stating that over the long term the exchange rate between two currencies adjusts according to currencies' relative purchasing power.
Investopedia Commentary
In other words, the exchange rate adjusts so that an identical good in two different countries has the same price when expressed in the same currency. For example, a chocolate bar that sells for CAD $1.50 in a Canadian city should cost USD $1.00 in a U.S. city when the exchange rate between Canada and the U.S. is 1.50 CAD/USD. (Both chocolate bars cost USD $1.00.)
